During normal operation it functions at DRAM speed. On power loss, the BBU powers the module long enough to flush DRAM contents to flash, preserving data across power cycles — unlike standard RDIMMs which lose data on power loss.\u003c\/dd\u003e\n\u003cdt\u003eDoes 874540-001 require a special backup power module?\u003c\/dt\u003e\n\u003cdd\u003eYes — HPE NVDIMMs require an HPE NVDIMM Backup Power Module (BBU) to enable the flash backup on power loss. Without the BBU, the NVDIMM may operate in DRAM-only mode without persistence. Consult HPE ProLiant Gen10 QuickSpecs for the required BBU part number.\u003c\/dd\u003e\n\u003cdt\u003eIs 874540-001 interchangeable with 845264-B21 and 825109-091?\u003c\/dt\u003e\n\u003cdd\u003eYes — 874540-001 is the spare part, 845264-B21 is the option kit, and 825109-091 is a factory\/OEM variant.
